Elasmobranch bycatch in the Italian Adriatic pelagic trawl fishery

Elasmobranchs are among the most threatened long-lived marine species worldwide, and incidental capture is a major source of mortality. The northern central Adriatic Sea, though one of the most overfished basins of the Mediterranean Sea, supports a very valuable marine biodiversity, including elasmobranchs. This study assesses the impact of the northern central Adriatic pelagic trawl fishery on...

Bycatch in the Maldivian pole-and-line tuna fishery

Tropical tuna fisheries are among the largest worldwide, with some having significant bycatch issues.

The Maldives has an important pole-and-line fishery, targeting skipjack tuna (Katsuwonus pelamis). In the Maldives, 106 pole-and-line tuna fishing days were observed ...

analysis of ruin probability for insurance companies using markov chain

در این پایان نامه نشان داده ایم که چگونه می توان مدل ریسک بیمه ای اسپیرر اندرسون را به کمک زنجیره های مارکوف تعریف کرد. سپس به کمک روش های آنالیز ماتریسی احتمال برشکستگی ، میزان مازاد در هنگام برشکستگی و میزان کسری بودجه در زمان وقوع برشکستگی را محاسبه کرده ایم. هدف ما در این پایان نامه بسیار محاسباتی و کاربردی تر از روش های است که در گذشته برای محاسبه این احتمال ارائه شده است. در ابتدا ما نشا...

Porpoise Monitoring in Pinger-net Fishery

Harbour porpoises are part of the assignment of 16 Natura 2000 areas in Danish waters and Denmark are obliged to monitor and protect the species. The harbour porpoise faces the threat of entanglement in gill nets but by using acoustic alarms, so-called “pingers” placed on the nets, bycatch can be reduced. Pingers may, however, scare the porpoises out of important areas such as the Natura 2000 a...
